June 7-10: American Astronautical Society held 16th annual meeting in Anaheim, Calif. Francis M. Stewart, MSFC Shuttle Engine Manager, and Ryndal L. Wetherington, NASA Hq. Space Shuttle Propulsion Manager, presented paper on main propulsion requirements for fully reusable Space Shuttle engine concept and new approaches to engine development and testing. Throttling to only 50% thrust satisfied system's needs and was baseline requirement. Value of one second of specific impulse had been calculated at $25 000000. Payload sensitivity of Space Shuttle concepts under study was 6900-8900 newtons (1500-2000 lbs per sec) of impulse. Minimum impulse per second in basic requirements represented 96% efficiency, "which has not been achieved in any rocket engine to date." Reusability requirement might be most difficult of all. "One can speculate that if we can do it in aircraft engines, why not rocket engines? But we are talking about heat fluxes and turbomachinery characteristics in the shuttle engine that extend well beyond those experienced in the engines of the Boeing 707, 747, or even the military high performance aircraft. It is yet to be shown if we can fly 100 missions (or even 10 or 20) with this high performance engine, and achieve the confidence and maintainability which the airline operations have in hand. . . reusability adds a new dimension to rocket engine development."

Prof. Yu. K. Khodarev, Deputy Director of Institute for Space Research of Soviet Academy of Sciences, and Dr. Valery Yevdokimov, head of Academy's data processing dept., called for studies of what U.S. and U.S.S.R. could do to establish and operate scientific base on moon. Prof. Khodarev said: "We would like to see concrete lists from American scientists of instruments that we could place on the moon for research. Then we can explore further avenues for cooperation in space. We can't decide how to transport things there until we first decide what we want to take." There was general acceptance of U.S.S.R. space efforts among Soviet people "but people are looking for a direct payoff-they want something for their money." Khodarev said U.S. and U.S.S.R. could "cooperate in a Martian program as well as in intense investigations on the moon." He suggested area for primary investigation from lunar station would have to be decided. "Do we want to look at the moon, or do we want to look into the cosmos from the surface?" During panel discussion Robert L. Lohman of NASA 's Space Station Task Force invited Prof. Khodarev to attend NASA meeting on advanced space programs at ARC later in year. Dr. Takao Ueda of Japan said Japan was working on comsats, TV satellites, and geosynchronous weather spacecraft. (AAS Paper No. 70-044; Bane, LA Her-Exam, 6/11/70; NASA Sci and Tech Info Div)
